The invention discloses a photovoltaic
cell maximum
power output control instrument based on a big
cane mouse optimization
algorithm, and relates to the field of photovoltaic
cell test instruments. The objective of the invention is to solve the problems that portability, high precision and multiple functions of an existing photovoltaic test instrument are difficult to consider, and the
maximum power point tracking efficiency is low and the stability is poor in a complex illumination environment. The controller comprises a shell, a main control module, a
voltage and current detection module, an illumination intensity detection module, a
voltage control module, an
oled screen display module, a
data transmission interface used for
data transmission and communication and the like. An MPP
tracking model based on a big
cane-mouse optimization
algorithm is provided, an illumination sudden change scene is adapted through an illumination gradient
influence factor, and an illumination stable scene is adapted by combining an adaptive step length optimization
perturbation and observation method. Microampere-level current measurement is achieved, MPP tracking time is prolonged by more than 70% when illumination suddenly changes compared with a traditional
perturbation and observation method, tracking precision is high, work is stable, portability is achieved, cost is low, and all-weather effective detection on multiple photovoltaic cells is supported.
